Yes it is a wireless mouse, but I had no problems through the first 66 levels. Also, I have tried exiting and restarting numerous times, checked all my settings, tried the touch-pad instead, put Bit Defender in game mode, you name it....I've tried it still no luck. You can see the mouse arrow briefly as the game loads but when it's fully loaded it disappears. Just thought maybe someone may have experienced the same problem.

I use a mouse on my Laptop also...I got to level 78 before I got sent back to level 68...due to a slow painful death, lol !
What I did notice is this is a heavy duty game...my fan on my laptop runs almost constantly when I play it...will have to try it on my Desktop...might be as the levels get harder it tasks the system more...I noticed when I exit my screen gets all goofy then clears up...then I wait for the fan to cease and desist before doing anything else!

Suki......hmmmmm can't really say I noticed my fan running extra hard or anything like that. In fact I had no problems at all till I quit playing at level 67 then, ever since, I have this mouse issue. Oh well......at least I enjoyed the first 66 levels.

Thanks Pookie....I'll give that a try......if I can get there. I have to move my mouse around "unseen" till one of the buttons lights up, that's the only way I can do anything. I'll let you know what happens.

Pookie......HEY GOOD THINKING! It worked! Took some work getting there....I had to go to my mouse settings and turn on the option to locate the mouse cursor by clicking the control key, then in the game I just kept hitting control till I could maneuver my arrow over the check-box. Once I got there and checked the box the problem was fixed. Thanks so much....you're a life saver.....well.......at least a game saver - hee hee.
